I am mapping a river and its changes (there will be a later followup topic on the best practice for mapping a much larger area of this river and its harbour once I understand the options here).
The following 2 images show an aerial view of the river in 1944 and the OHM map for the current river profile/shoreline, which currently has no start_date.
I can easily show in OHM the addition of land with time by adding a river area with no start-date and an end_date somewhere between 1944 and now. There seems to be no corresponding ‘land’ area shortcut that I can use to map the loss of land. Is the proper way to break the river into segments with their own start and and end dates? I suspect that the answer is YES once I consider the adjacent land features such as the mangrove areas, which also change with time, but it would be nice if there was a ‘lose land’ shortcut for minor changes.
